             *

Answer 1

I'd suggest setting up your drawer using the NavigationView class from the Android design support library, which also allows menu inflation from xml resources. You'd then handle clicks by registering a NavigationView.NavigationItemSelectedListener

Its very Simple implement OnClickListener in your ViewHolder and then in onClclick method use getAdapterPosition() method. please check the code given below.. It will help you

 public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        public ViewHolder(View itemView) {
            super(itemView);
            itemView.setClickable(true);
            itemView.setOnClickListener(this);
        }

        @Override
        public void onClick(View view) {
            Log.e(TAG, "POSITION " + getAdapterPosition());
            switch (getAdapterPosition()) {
                case 0:
                    break;
                case 1:
                    break;
                case 2:
                    break;
            }
        }
    }
